Specification of Letters Patent. Patgnted NQV- 3Q 1915,

Application filed December 9, 1912. Serial No. 735,681.

I To all whom it may concern Be it known that I, HERBERT E. WHITE, a citizen of the United. States, residing at Youngstown, in the county of Mahoning and State of Ohio, have invented certaln new and useful Improvements in Paint.

Spraying Devices, of which the following is a specification.

features of construction whereby the paint or coating medium can be quickly and effectively applied to bothsides of the expanded metal without excessivewaste of the paint.

It has been found impractical to use the ordinary spraying devices for painting expanded metal or similar perforate articles, owing to the fact that much of the paint or coating medium passes through the per forations and is wasted, and among the objects of the present invention is to provide a device in which this objection is overcome by oppositely disposed nozzles which are arranged upon'opposite sides of the member to be coated and produce jets which "meet in substantially the plane of the said member so as to produce a veritable atmosphere of the coating medium.

A further object of the invention is to provide a spraving or coating device which is comparatively simple and inexpensive in its construction, which is continuous in its operation, and which admits of the nozzles being readily adjusted so as to always obtain the best results.

With these and other objects in view, the invention consists in certain novel combinations and arrangements of the parts as will more fully appear as the description proceeds, the novel features thereof being pointed out in the appended claims.

For a full understanding of the invention, reference'is to be had to the following description and accompanying drawings, in which Figure 1 is a top plan view of a paint spraying device constructed in accordance with the invention, portions being broken away. Fig. 2 is a side elevation of the same,

portions being broken away and shown in section, and Fig. 3 is a transverse vertical sectional view through the device.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

Specificallydescribing the present embodiment of the invention, the reference character A designates an endless conveyer which may be of any suitable construction and upon'which the expanded metal membersl are placed. This conveyer A is shown as comprising the two chains 2' which are connected by the transverse supporting rods 3 and pass around the sprockets 4 upon the shaft 5. Power may be applied to the shaft 5 in any suitable manner for the purpose of driving theconveyer and carrying the expanded metal members 1 thereon between the opposed upper spraying nozzles 6 and lower spraying nozzles 7 'The upper and lower spraying nozzles 6 and 7 are carried by a frame B through which the upper reach of the endless conveyer A passes. This nozzle carrying framev B is substantially rectangular in shape and isformed with tubular end pieces 8 and 9, the middle portion of the end piece 8 communicating with and being swiveled at 10 to a main air supply pipe 11, while in asimilar manner the middle portion of the tubular end piece 9 communicates with and is swiveled at 12 to a main paint supply pipe 13. These two swiveled joints 10 and 12 have an opposed relation and are in alinement with each other so that the nozzle carrying frame B can be swung about a substantially horizontal axis or an axis in the plane of the member being coated.

The top and bottom of the nozzle carrying frame B each comprise a pair of tubular members 14 and 15 which are arranged side by side, the member 14 communicating with the tubular end piece 9,

while the member 15 communicates with.

arm 17 will serve to supply Compressed air to the nozzles, the passage of compressed air through the nozzles acting in the usual" manner to produce suction and eject the paint in the form of a spray.

The various nozzles 6 and 7 are pivotally mounted between the arms 16 and 17 so as to turn freely about a horizontal axis or an axis parallel to the member 1 being-coated. This admits of the upper and lower nozzles 7 and 8 respectively being adjusted upon the nozzle carrying frame B so as to operate in the most effective manner upon the expanded metal or metal lath. As has been previously explained, the nozzle carrying frame B can also be tilted as may be required. In Fig. 2, the nozzle carrying frame B is shown by full lines in an 'upright or vertical position, and by dotted lines as tilted into an inclined position. This same figure of the drawing also serves to illustrate the manner in which the nozzles can be adjusted with respect to the frame B, the said nozzles being shown by lines as tilted into positions at an angle or inclination to the plane of the frame B, so that the jets therefrom meet each other at an angle, and by dotted lines as swung into a directly opposed relation.

Thejets of paint or coating material from the upper and lower opposed nozzles 6 and 7 meet' substantially in the plane of the expanded metal member 1 so as to produce a veritable atmosphere of the coating material, through which the said expanded metal member is moved by the conveyer. Both sides of the. expanded metal member are thus efi'ectivelycoated, and owing to the opposed rial or paint is avoided.

relation of the, nozzles and the meeting of the jets in the plane of the member, the usual and objectionable waste of the coating mateswing the nozzles toward or away from the member being coated. e

'2. A device for coatingpxpanded metal and the like, including oppositely disposed and adjustably mounted spraying nozzles arranged on opposite sides of the member to be coated so that the jets therefrom meet substantially in the plane of the said member, and a pivotally mounted supporting frame carrying the nozzles, the said support ing frame being adapted to be tilted about its axis to swing the nozzles toward or away from the member being coated and the nozzles themselves being adjustable so that the inclination thereof with respect to the frame can be varied.

3. A device for coating expanded metal and the like, including conveying means for the member to be coated, a swinging frame mounted to turn about an axis substantially in the path of the said member, and-oppositely disposed nozzles adjustably mounted upon the swinging frame and arranged on opposite. sides of the path of the member so as to be moved toward and away from the same as the frame is swung about its axis,

' the jets from the nozzles meeting in the path a of the member so as to produce an atmosphere of the coating material through which the member is conveyed, and the inclination of the nozzles with respect to the frame being adjustable as desired.

a. A device for coating expanded metal and the like, including a frame formed with tubular end pieces connected by opposed sides, an a r supply pipe communicating with one of the tubular end pieces, a coating material supply pipe communicating with the opposite tubular end. piece, oppositely disposed nozzles mounted upon the sides of the frame and communicating with the respective tubular end pieces thereof so as to receive a continuous supply of air and coating material, and means for supporting the member to be coated between the nozzles. r

'5. A device for coating expanded metal 1 and the like, including a frame formed with tubular end pieces, an air supply pipe communicating with and having a swiveled connectlon with one of the tubular end pieces,

a coating material supply pipe communieat- .mg with and havmga swiveled connection with the opposite tubular end pieces, the frame being adapted to be swung about its swiveled connections with the air supply pipe and coating material supply pipe, op- I posed nozzlescarried by the frame and communicating with the tubular .end pieces so as to receive a continuous supply of air and coating material, and means for supporting a member to be coated between the nozzles.

" 6. A device for coating expanded metal and the like, including a frame formed with tubular end pieces and connected by sides,

the said sides being each formed with a pair I of tubular members arranged side by side and communicating with the respective end pieces, a pair of tubular arms projecting from each side and communicating with the respective tubular members of the sides, op- I positely disposed nozzles mounted between the tubular arms, an air supply pipe in communication with one of the tubular end pieces of the frame, a coating material supplv pipe in communication with theopposite T tubular end piece of the frame, and means of a pair of tubular members communicafl ing with the respective end pieces,- an air supply pipe communicating with and having a swiveled connection with one of the end pieces, a coating material supply pipe communicating with and having a swiveled connection with the opposite end piece, the frame being adapted to be tilted about its connections with the air supply pipe and coating material supply pipe, a pair of tubular arms projecting from each'of the side pieces of the frame and communicating with the respective tubular members thereof, nozzles mounted between the arms so as to receive a continuous supply of air and paint through the opposite tubular end pieces of the frame, and means for supporting a member to be coated between the nozzles.

In testimony whereof I hereunto'afiix my si nature in the presence of two witnesses.
